To all whomz't may concern:

Be it known that 1, JOHN J. So LLY, a

citizen of the United States of America, and

1 ing-machine spring'motor which motor is surrounded by a casing the wall of which is relatively remote from the arbor, being to its fiared outer end sometimes spaced as far asten or twelve inches therefrom. As the point of engagement of the crank with the arbor is entirely concealed, it is frequently difficult to bring the mating ends of the crank and operative engagement. /Usually the arborarbor into connecting. end of the crank is blindly gyrated within the casing on the casing wall escutcheon'as a fulcrum until, more or less accidentally, connection is made with the arbor. The futile attempts at making connection with the arbor cause annoyance.

, This is to be regretted because the'whole' purpose of the talking -machineis to give pleasure.

It is an object of this invention to provide means whereby thefcrank' may be promptly brought into operative engagement with the arbor, thus avoiding the annoying delays 7 and difficulties indicated above.

The invention will be described in connection with the accompanying drawings in which,

Figure 1 is an inverted plan view on talking machine providedwith an embodi ment of the present invention and showing the winding arbor and crank in separated relationship and the guide member partially broken away for the sake of clearness; and

Fig. 2 is a detailed view, on an enlarged scale, of one form of the guide member. Referring in detail to said drawings, 1

designates a spring motor of any suitable construction, the same being shown as a I '7 3 driving element of a talking machine of any preferred construction. 2 designates a surrounding casing provided with an escutcheon 3 through which the winding crank 4 is inserted'into engagement with the winding arbor of said motor. In the form shown, said arbor takes'the form of a tubularshaft 5 carrying a pinion6 and rotatably mounted in any suitable way as in the Patented Au 31', fiezj'og bracket 7.; Said arbor 5 is shown as provided with interior screw-threads for coaction with exterior threads 8 on theend of crank 4. To the arbor is suitably connected a funnel-shaped guide member 9 which is "shown as provided with-a flared outer end through the escutcheon 3 and guides the same into operative engagement with the arb0r.. Thereby the crank may be quickly brought into operative engagement with the arbor and, in the form shown, rotated to en-' gage the threads 8 with the threads 7 for and arbor. even though the distance between the wall of connecting the mating sections of said crank It will therefore'be seen that,

the casing 2 and the end ofthe winding ar-- bor be relatively great, the winding crank may be 'brought'into operative relation to thearbor'promptly, and withoutexperimentation and annoying delays incident to the engagement of the crank with thearbor prior devices. I 7

While the preferred mechanical expression of the invention has been described with "considerable particularity it is obvious that various changes may be made in the de-' tails of construction without. departing from this invention'and it is, therefore, to

be understood that this invention is not to:

be limited to the specific construction.

What is claimed is p I 1. In combination, a spring motor having a winding arbor, a sleeve telescoped over said-arbor and secured thereto, a wall spaced from said arbor and having an opening therein, a winding shaft projecting through 2. In combination, a spring motor having 'said'opening, and a funnel-shaped member 7 carried by said sleeve ,and facing said opena winding arbor, a sleeve telescoped over 7 said arbor,

a collar telescoped over said sleeve, means carried by the collarfor secur 2 I a I 1,351,405

shaped member carried by said sleeve and facing said opening.

3. In combination, a spring motor having a Winding arbor, a Wall spaced therefrom and having an opening therein, a Winding shaft projecting therethrough, and a guid- 10 mg means for said shaft comprising a sleeve teleseoped over and secured to said arbor, and 'a funnel-shaped extension coaxial with said sleeve and facing said opening.

In testimony whereof I have signed this 15 specification.
